The Red Admiral has a very erratic, rapid flight, flight time from July to October.

The Admiral lives in the mild areas of Central Europe,
throughout the year. Due to the climate change it hibernates increasingly also in northeast. In mild
winter also young larvae or pupae can survive.
The Admiral is often observed on fallen fruit in the fall while
vacuuming.

The caterpillars live on the nettle.

Red Admirals prefer sap flows on trees, fermenting fruit,
and bird droppings; visiting flowers only when these are not available. Then
they will nectar at common milkweed, red clover, aster, and alfalfa, among
others.

In northern Europe, it is one of the last butterflies to be
seen before winter sets in.
